Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08E
The AirTAC Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08E is a genuine double-acting ISO 15552 cylinder with a Ø32mm bore, 500mm stroke and a built-in 4M210-08 5/2 solenoid valve — it switches itself from one coil signal, so no separate remote valve or extra plumbing is needed.

About the Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08E
The AirTAC SAIF32X500S-08E is a double-acting ISO 15552 profile cylinder with an integrated 4M210-08 5/2 solenoid valve, yielding a Cv of 0.89 and a 16.0 mm2 orifice. Driven by an AC24V terminal coil consuming 3.5 VA, it responds in 0.05 s with IP65 protection. The cylinder body rates to 1.0 MPa, but because the internal pilot valve operates at 0.15-0.8 MPa, the practical working range for this assembled unit is 0.15-0.8 MPa. At 0.5 MPa it generates 402 N of push force and 345 N of pull force.
This 32 mm bore unit includes a magnet for position sensing and is compatible with AirTAC CMSE reed and DMSE electronic sensors. The manifold links the valve to the cylinder using O8 x O5 PU tubing, and the valve's 1/4 inch port differs from the cylinder's PT1/4 port. Factory-set to retract the rod when the coil is energised, the valve can be repositioned to extend-when-energised. It switches itself from one coil signal, eliminating remote valves and reducing panel space for decentralized stations.

The cylinder rates to 1.0 MPa but the built-in valve operates 0.15–0.8 MPa, so run the assembled SAIF at 0.15–0.8 MPa. Default: rod retracts when the coil is energised (reconfigurable to extend). Specs follow the official AirTAC SAIF datasheet. Port options: PT / G.

| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | — |
Sized within the valve's 0.15–0.8 MPa range. Actual usable force is lower than theoretical due to friction and back-pressure.

SAIF does not hold its load without air — the valve routes air, it is not a lock. For load-holding use a SAIL (lock) or BSAI (clamp-lock).
Where the Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08E Is Used
Decentralized Automation
Ideal for large machines with distributed stations, eliminating long air lines from a central valve bank by switching directly from the AC24V coil signal.
Extended Stroke Handling
The 500 mm stroke suits long-travel positioning tasks, provided external guides are used to manage rod side-loading on this 32 mm profile cylinder.
Space-Constrained Retrofitting
Fits easily into tight machine envelopes where adding separate valves and tubing is impractical, offering a compact 5/2 valve manifold and PT1/4 connections.
Is the Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08E the Right Choice?
Choose this 32 mm bore if your application requires around 402 N of push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N. The 500 mm stroke is substantial for this profile cylinder, so ensure adequate guiding to prevent rod side-loading and premature seal wear. This self-valved SAIF configuration is superior to a separate cylinder and remote valve when you want to minimize plumbing and wiring across decentralized machine stations. When specifying a replacement, match the 32 mm bore, 500 mm stroke, 08 valve port, AC24V voltage, terminal entry, PT thread, and the -S magnet requirement. Remember the 5/2 valve routes air but does not lock the load; for position holding, consider the SAIL lock series.
Quick checklist
- ✓ Force at 0.15–0.8 MPa
- ✓ Coil voltage matches panel
- ✓ Terminal vs grommet entry
- ✓ Retract- or extend-when-energised
- ✓ Load-holding → SAIL / BSAI
Airtac SAIF Series Standard Cylinder with Valve SAIF32X500S-08E FAQ
At 0.5 MPa, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. While the cylinder body rates to 1.0 MPa, the built-in 4M210-08 valve operates at 0.15-0.8 MPa, making 0.15-0.8 MPa the practical working range for this unit.
Yes. The factory setting retracts the piston rod when the AC24V coil is energised, but you can reconfigure it to extend-when-energised by repositioning the 5/2 valve. This allows you to control the fail-safe state of the double-acting cylinder from a single coil signal without needing a separate remote valve.
